Chase

A temperature-dissolved oxygen profile was collected in the deepest basin on Chase Lake on August 1, 2023, to evaluate the amount of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee. Based on the profile, the top of the thermocline (i.e., the location in the water column with the sharpest transition from warm to cold water) occurred at approximately 23 feet. Dissolved oxygen decreased to below 3.0 mg/L at 51.9 feet, which was below the thermocline, at the time of sampling. The temperature at which dissolved oxygen decreased to below 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 5.4°C (41.7°F). TDO3 values cooler than 21.5°C indicate that oxythermal conditions are favorable for Cisco. Dissolved oxygen concentrations below the thermocline indicate that suitable oxythermal habitat for Cisco was available across a range of depths at the time of sampling during the summer of 2023. Data collected in 1976-2016 further indicate suitable oxythermal habitat across years, with the least favorable conditions recorded in 1981. When inadequate oxythermal habitat is available, Cisco are squeezed into unfavorable, warmer water conditions and therefore experience higher levels of stress.

Based on Minnesota DNR survey data, anglers target Largemouth Bass, Black Crappie, Northern Pike, Pumpkinseed, and Yellow Perch in Chase. See the full species list above for catch rates, size structure, and quality scores.

We don't have a confirmed public access point on record for Chase. Check the DNR LakeFinder page for current access details before you go.

Chase has a maximum depth of 95 feet, per Minnesota DNR data.

The most recent Minnesota DNR survey data for the main sport fish in Chase is from 2016. Surveys this old should be treated with some caution — fish populations change over time.

No invasive species are on record for Chase in Minnesota DNR data. Always clean, drain, and dry your equipment to help keep it that way.
